Solving One Step Equations
Addition Equations
Learn how to solve one step equations in 2 easy steps.
There are four things that you must remember when solving any equation AND everything must be mathematically correct!
- Your goal is to get the variable that you are solving for by itself on one side of the equation.
Example: x = _____ - To eliminate a term on one side of the equation, you use the opposite mathematical operation.
- Whatever you do to one side of the equation, you MUST do to the other side of the equation. This keeps the equation balanced!
- Always check your answer by substituting the value back into the original equation.
Let's take a closer look at the three rules above in an example problem.
Example 1
If you'd like to see more examples on video, check out the Solving Equations E-course. You'll find not only more step-by-step examples on video, but you'll also find practice problems with step-by-step solutions.
Here we have two more examples of how to solve a one step addition equation! I've even thrown in a few negatives, because that can sometimes confuse you, especially if you don't remember your addition integer rules or your subtraction integer rules.
Example 2
Example 3
Addition equations are pretty easy to solve. Remember that the opposite of addition is subtraction, and whatever you do to one side, you must do to the other side!

What People Are Saying...
"I'd like to start off by relaying my sincerest gratitude for your dedication in teaching algebra. Your methodology is by far the simplest to follow, primarily because you take the time to include the small steps in between that most other teachers leave out.
It helps to know why you are doing something. I am 45 and heading to college to get my BS in Business. I need to brush up, hence the visit to your site. Great Job!"

"I stumbled onto your site after I found out that I needed to use some fundamental algebra for an assignment. Turns out I had forgotten some things and your great site helped me remember them like "that" (snap of fingers). The organization of the site let me find exactly what I was looking for so easily. Kudos to you for maintaining such a great resource for students of all ages!"

"I just wanted to write and basically thank you for making such a wonderful website! I'm 20 years old and about to take a basic placement test for college. I wanted to brush up on my Algebra skills and I stumbled upon your site. I'm amazed at how simple you make it and how fast I'm remembering Algebra! I don't remember getting most of the answers right when I had an actual teacher in front of me teaching this. Thanks a lot!"

"I am a pensioner living in South Africa. I stumbled on your website, the best thing that could ever happen to me! Your course in Algebra has helped me a lot to better understand the different concepts. Thank you very much for sharing your skills for teaching math to even people like me. Please do not stop, as I am sure that your teachings have helped thousands of people like me all over the world."

This is an amazing program. In one weekend I used it to teach my Grade 9 daughter most of the introductory topics in Linear Relations. I took her up to Rate of Change and now she can do her homework by herself.
